Performance parameters of liquid ring compressors
The performance parameters of liquid ring compressors mainly include the following:
Exhaust pressure: Exhaust pressure refers to the pressure of the gas generated by the liquid ring compressor during operation when it is discharged from the system. It directly affects the outlet flow and power consumption of the liquid ring compressor. Generally, the higher the exhaust pressure, the smaller the outlet flow of the liquid ring compressor and the greater the power consumption.
Compression ratio: The compression ratio refers to the ratio of the exhaust pressure of the liquid ring compressor to the inlet pressure, which reflects the degree to which the liquid ring compressor compresses the gas. When the compression ratio is too high, the power consumption and temperature rise of the liquid ring compressor will increase, and its efficiency will be reduced. Therefore, reasonable control of the compression ratio is the key to optimizing the performance of the liquid ring compressor.
Operating speed: The operating speed of the liquid ring compressor refers to the speed at which its rotor rotates. Appropriately increasing the operating speed can increase the flow, but it will also lead to an increase in power consumption and an increase in vibration and noise.
Cooling water temperature: The liquid ring compressor uses cooling water to reduce the temperature rise and maintain the stable operation of the compressor. Changes in cooling water temperature will directly affect the efficiency and power consumption of the liquid ring compressor. If the cooling water temperature is too high, the temperature rise will increase and the efficiency will be reduced; if the temperature is too low, the energy consumption of the cooling water will increase.
Sealing water volume: Sealing water volume refers to the water flow used for liquid ring seal and shaft seal. Appropriate sealing water volume can maintain the sealing performance of the liquid ring compressor and prevent gas leakage, but too much sealing water volume will increase power consumption.
Exhaust gas temperature: Exhaust gas temperature refers to the temperature of the gas discharged by the liquid ring compressor during operation. The increase in exhaust gas temperature will lead to a weakened cooling effect, which in turn affects the performance and life of the liquid ring compressor.
Liquid ring temperature: The liquid ring temperature is the operating temperature of the liquid in the liquid ring compressor, which has an important impact on the performance and efficiency of the compressor.
